Terms of use

Last updated 7 October 2026

By using TatamiChess, you accept these terms.

The service

TatamiChess is a chess opening trainer, provided as is. Its features may change over time.

Your account

Keep your password to yourself. You can delete your account at any time in Settings.

Acceptable use

Don't misuse the service: no attempts to break it, overload it, copy it in bulk or access other people's accounts. We may suspend accounts that do.

Your content

Your repertoires and progress remain yours. You allow us to store and process them only to provide the service.

Chess data

Games and opening statistics come from chess.com and Lichess and remain subject to their terms. TatamiChess is not affiliated with either. Engine evaluations are training aids, not guarantees.

Liability

To the extent permitted by law, we are not liable for indirect damages. This does not affect your rights as a consumer.

Changes and applicable law

We may update these terms; the date at the top shows the latest version. These terms are governed by French law, without prejudice to the consumer protection of your country of residence.
